Man who killed two firefighters in Webster left chilling note; missing sister's body found in home

WEBSTER -- An ex-con killed two firefighters with the same caliber and make military-style rifle used in the Connecticut school massacre after typing a note pledging to burn down his neighborhood and "do what I like doing best, killing people," police said Tuesday as another body, believed to be the gunman's missing sister, was found.

William Spengler, 62, who served 17 years in prison for manslaughter in the 1980 hammer slaying of his grandmother, set his house afire before dawn Christmas Eve before taking a revolver, a shotgun and a semiautomatic rifle to a sniper position outside, Police Chief Gerald Pickering said.

The death toll rose to three as police revealed that a body believed to be the killer's 67-year-old sister, Cheryl Spengler, was found in his fire-ravaged home.

Authorities say he sprayed bullets at the first responders, killing two firefighters and injuring two others who remained hospitalized Tuesday in stable condition, awake and alert and expected to survive.

He then killed himself as seven houses burned on a sliver of land along Lake Ontario.

Police recovered a military-style .223-caliber semiautomatic Bushmaster rifle with flash suppression, the same make and caliber weapon used in the elementary school massacre in Newtown, Conn., that killed 26, including 20 young children, Pickering said.

The chief said it was believed the firefighters were hit with shots from the rifle given the distance, but the investigation was incomplete.

"He was equipped to go to war, kill innocent people," the chief said.

The two- to three-page typewritten rambling note left by Spengler did not reveal what set off the killer or provide a motive for the shootings, Pickering said.

He called the attack a "clear ambush on first responders."

He declined to reveal the note's full content or say where it was found. He read only one chilling line: "I still have to get ready to see how much of the neighborhood I can burn down, and do what I like doing best, killing people."

Pickering said it was unclear whether the person believed to be Spengler's sister died before or during the fire.

"It was a raging inferno in there," Pickering said.

A next-door neighbor said Spengler hated his sister and they lived on opposite sides of the house.

Roger Vercruysse said Spengler loved his mother, Arline, who died in October after living with her son and daughter in the house in a neighborhood of seasonal and year-round homes across the road from a lakeshore popular with recreational boaters.

Spengler had been charged with murder in his grandmother's death but pleaded guilty to a reduced charge of manslaughter, apparently to spare his family a trial.
